Our view is that the ethylene pathway is likely to be the most
achievable of the gas upgrading options for smaller scale gasification
(1-5 tonnes/hr feed rates). Produced as a co-product through a dedicated
retort with depleted exhaust gases from this used to fuel a generator.
Ethylene is relatively easy to form from CO & H2 as the catalytic retort
needed operates at very modest temperatures and pressures (300oC &
150psi). The ethylene produced can then be compressed and transported as
for LPG. It could be added to existing reticulated natural gas lines,
used directly as a transport fuel or as a feed stock for ethanol &/or
plastics manufacture. The ultimate in recycling, generating virgin
material from used. When we are over the current speed bumps on our
journey we might have a crack at it (excuse the pun).
